Life-Like Proto 1000 RDC-1 Undercarriage

[?]Does anyone know where I can find a plastic undercarriage for the Life-Like Proto 1000 RDC-1? The metal undercarriage frame seems awkward.

Why? Awkward how?

Replacing the heavy metal frame with a light plastic frame will probably make a drastic decrease in tractive power. Heavy is good!
